Rivals Iran and UAE hold maritime security talks

"The sixth joint coastguard meeting between Iran and a visiting seven-member delegation from the UAE will be held in Tehran in order to discuss border cooperation between the two countries," state news agency IRNA said, citing a statement from Iran's foreign ministry.

"The two countries are set to talk about issues related to shared borders, visits by citizens, illegal entries and facilitating information sharing," the agency added.

A Gulf official speaking to AFP on condition of anonymity said the two sides had "a regular coordination and technical meeting related to the topic of fishermen and other similar topics."

The Tehran meeting "has nothing to do with the recent regional tensions," the official added.

Tensions have increased in sensitive Gulf waters following a series of mysterious attacks on tankers off the UAE coast and the Gulf of Oman.

Washington and its Gulf Arab allies blamed Iran for the attacks, charges Tehran categorically denies.

The United Arab Emirates is part of a Saudi-led military coalition fighting Iran-aligned Shia Houthi rebels in Yemen.

Tehran is also at loggerheads with Washington over US President Donald Trump unilaterally withdrawing from the 2015 nuclear agreement last year and reimposing sanctions on Iran.
